Took a while to do the editing and voiceover (first time I've ever made a proper video in all honesty), but I'm finally done with the whole run which I'm pretty happy with.
You can watch the video on my youtube (I won't link it in order to not be directly self promoting), but the run revolves around the 3 primary issues that come up:
1. The wrong weather on day one (hardcoded sunny weather)
2. A lack of fishing rod (Willy's out of town on day 1)
3. The fishing level 10 catch requirement
It uses 4 main glitches to solve them, name injection, item IDs, buff stacking, and save state trash abuse. The name injection is to force the game to run a mail check out of order and a workaround to avoid a too-long name, the item ID is for getting around the weather (can't be done otherwise unfortunately), and save states allow me to force multiple wanted trash items (alongside a specific seed that accounts for the day 0 steps from the intro cutscene) as well as to level up beyond what's normally possible with buffs, all coming together pretty neatly in the end.
Thought I'd share here as a few people were curious how this was possible.
silly me
